Import Products - Correcting format

Ok, how should I do these things?

My supplier CSV doesn't import very well in a few places.

COLUMN ISSUE ONE
Photos - I have three photos per item. The small, medium and large photos.

In Hikashop, it only seems to have 1 IMAGES column. How can I import all three images.


COLUMN ISSUE TWO
Categories - supplier column has this format level1>level2>etc

What should be the format for import if I have a product categories like this:

Apparel>Tees
Apparel>Tees>Short Sleeve
Apparel>Tees>Long Sleeve

All the images need to be in one column:
product_code,images
my_prod,"image1.png,image2.png,image3.png"

If you already have your categories tree in hikashop, all you need to do is to specify the last level:
product_code,categories
my_prod,Long Sleeve

Otherwise, you need to have something like that:
product_code,parent_category_categories
,Apparel,Tees
,Tees,Long Sleeve
my_prod,,Long Sleeve

That way, the system will also create the categories tree before importing the product.
